Ch. 4 Review Vocabulary Words

Question 1

Asexual Reproduction

Answer 1

A new organism is produced from one organism.

Question 2

Chromosome

Answer 2

A chromosome is a structure in the nucleus that contains hereditary material.

Question 3

Diploid

Answer 3

When cells have pairs of similar chromosomes, they are said to be diploid.

Question 4

DNA

Answer 4

A cell also uses a code that is stored in its hereditary material the code is a chemical called deoxyribonucleic acid, or DNA.

Question 5

Egg

Answer 5

Eggs are formed in the female reproductive organs.

Question 6

Fertilization

Answer 6

The joining of an egg and a sperm is called fertilization.

Question 7

Gene

Answer 7

The instructions for making a specific protein are found in a gene with is a section of DNA on a chromosome.

Question 8

Haploid

Answer 8

Because sex cells do not have pairs of chromosomes, they are said to be haploid. They have only half the number of chromosomes as body cells.

Question 9

Meiosis

Answer 9

A process called meiosis produces haploid sex cells.

Question 10

Mitosis

Answer 10

The process in which the nucleus divides to form two identical nuclei is mitosis.

Question 11

Mutation

Answer 11

Mutations are any permanent change in the DNA sequence of a gene or chromosome of a cell.

Question 12

RNA

Answer 12

The codes for making proteins are carried from the nucleus to the ribosomes by another type of nucleic acid called ribonucleic acid, or DNA.

Question 13

Sexual Reproduction

Answer 13

During sexual reproduction, two sex cells sometimes called and egg and a sperm, come together.

Question 14

Sperm

Answer 14

Sperm are formed in the male reproductive organs.

Question 15

Zygote

Answer 15

The cell that forms from an egg and a sperm is called a zygote.

Question 16

Parent Cell

Answer 16

The Original Cells.

Question 17

Daughter Cell

Answer 17

Two new cells created after cell division process.

Question 18

Cytokinesis

Answer 18

The cytoplasmic division of a cell at the end of mitosis or meiosis, bringing about the separation into two daughter cells.

Question 19

Apoptosis

Answer 19

The death of cells which occurs as a normal and controlled part of an organism’s growth or development.

Question 20

Spindle Fibers

Answer 20

Spindle fibers form a protein structure that divides the genetic material in a cell.

Question 21

Chromosomes

Answer 21

Structure in a cell’s nucleus that contains hereditary material.

Question 22

Centrioles

Answer 22

A centriole is a small structure made of microtubules which exists as part of the centrosome, which helps organize microtubules in the body.
